In the May 11 & 25 SN: High-tech cricket farming, AI learns from Minecraft, looking for lithium, a new hominid species is named, signs of life in dead pig brains, Cherokee cave texts decoded, water molecules on the moon and more.

There’s no sorrier sight than a puking preschooler. That’s the conclusion I recently reached around 2 a.m. as my poor 4-year-old heaved into the dim abyss. Luckily, her bout with the stomach flu was brief, and she was feeling better by the next day.

Stomach flu, also known as gastroenteritis, is a common affliction caused by bacteria or viruses that inflame the gut. Though mercifully...

I love to hate the phrase “sleep like a baby.” It’s a beautiful example of a saying that’s based on the exact opposite of what it’s intended to convey. Babies (many of them, anyway) are rotten sleepers.

During my last pregnancy, I wondered if I might luck out with a good sleeper. Or at least an average sleeper. But my third little sweetie didn’t deliver. At nearly 8 months, he (and I)...

Sometime around 9 p.m., before the second leg of a cross-country flight, my just-turned-4-year-old decided she had had enough. She let out a scream and went full noodle right at the end of a moving walkway in Chicago Midway. I had the baby in a carrier and a death grip on my older daughter’s hand, so it was up to my husband to scoop up our enraged, sweaty middle child and keep hold of her and...

I’m making my way through my third round of breastfeeding a newborn and taking stock of how things are going. Some aspects are definitely easier: My milk came in really quickly (a perk of being a repeat lactator), the fancy breastfeeding baby holds are no longer mysterious to me and I already own all of the weird pillows I need to prop up my tiny baby.

Getting help from a toddler is a bit like not getting help: They mean well, but you may end up with more of a mess than when you started.

But given the choice, many kids prefer “real” activities to imaginary games, Bruce Bower recently reported in depth for Science News. And the benefits of recruiting your child for help with chores may go beyond conquering that pile of laundry: Research...

Like millions of parents, I post pictures of my kid on Instagram. When she was born, her father and I had a brief conversation about whether it was “dangerous” in a very nebulous sense. Comforted by the fact that I use a fake name on my account, we agreed to not post nudie pics and then didn’t give it much more thought. Until recently.

Hunter-gatherers and farming villagers don’t write parenting handbooks, much less read them. But parents in WEIRD societies — Western, educated, industrialized, rich and democratic — can still learn a few childrearing lessons from their counterparts in small-scale societies.

It’s not that Western parents and kids are somehow deficient. But we live in a culture that holds historically...

The holiday onslaught is upon us. For some families with children, the crush of holiday gifts — while wonderful and thoughtful in many ways — can become nearly unmanageable, cluttering both rooms and minds.

This year, I’m striving for simplicity as I pick a few key presents for my girls. I will probably fail. But it’s a good goal, and one that has some new science to back it. Toddlers...

When you lock eyes with a baby, it’s hard to look away. For one thing, babies are fun to look at. They’re so tiny and cute and interesting. For another, babies love to stare back. I remember my babies staring at me so hard, with their eyebrows raised and unblinking eyes wide open. They would have killed in a staring contest.
